Main Graph Editor Starting

# Starting the Graph Editor

Before editing a graph, you have to connect the editor to the uDraw(Graph) API. This can be done with the user interface at run-time with menu File/Connect Application.... Simply navigate with the file browser and select the graph editor executable file named "grapheditor(.exe)" in the "bin" directory of the uDraw(Graph) distribution. Note: if you do not know where uDraw(Graph) is installed on your computer, then display the environment variable $UDG_HOME in a command-line or ask your system administrator.

## Graph Editor Modes

Another way to connect the graph editor is by starting uDraw(Graph) and the editor at the same time using one of the command-line options -graphedit (referred to as "-graphedit mode" for the rest of the graph editor chapter) or -graphedit_old (referred to as "-graphedit_old mode").

## User Interface Reconfiguration

When connected initially using option -graphedit, the graph editor will slightly reconfigure the uDraw(Graph) user interface to add additional entries in the menus usually reserved for uDraw(Graph) operations (namely menu entries "View/Open New Graph in New View" and "Help/Grapheditor"). User interface reconfiguration is a new feature since version 3.0. Reconfiguration only works at start-up time of uDraw(Graph), so you will not see these additional menu entries when you connect the editor at run-time using menu File/Connect Application.... When you disconnect the editor by menu, all uDraw(Graph) windows will disappear for a short time to reset user interface reconfigurations. Afterwards you will see the standard user interface which is mostly identical to the interface configured by the graph editor.
